Fig 1. Characteristic histopathological findings observed in postmortem examination.
A, pulmonary dysplasia in gross; B (the contralateral lung), C (the ipsilateral lung) Relatively normal lung development bilaterally was showed in left CDH , hyaline membrane formation in the alveolar space, diffuse pulmonary hemorrhage, widened alveolar septa were found ((hematoxylin and eosin (HE), × 200); D (the contralateral lung), E (the ipsilateral lung) underdeveloped lung structure at canalicular period in both lungs showed in right CDH with decreased number of alveoli, and diffuse alveolar edema and hemorrhage with hyaline membranes, marked inflammatory cell infiltration were found (HE, × 100); F, lung structure development was fair, alveolar hyaline membrane was found(TTF-1, × 200); G, pulmonary hemorrhage, hemosiderin cells found in the lung (HE, × 200); H, aplasia of the musculature within the leaflet of the ipsilateral diaphragm (HE, × 100); I, ipsilateral diaphragm calcification necrosis, inflammatory cell infiltration in right CDH (HE, × 200)
